SPEGIFIGATIONformihg part of Letters Patent No. 790,092, dated May 16, 1905.

' Application filed February 9, 1903. Serial No. 142,585.

Among the main objects of my invention are to simplify and reduce in number and cost thev parts necessary to make up a lock of that type which is inserted in a notch in the stile of a door. The simplicity and compactness of the.

parts avoids the necessity of cutting away but a very slight portion of the door. Other advantages will be apparent to the mechanic skilled in the art from a reading of the following specification.

- In the accompanying drawings, Figure 1 is a sectional plan view of my lock, the plane of the sectioned portions extending through the axis of the knob. Fig. 2 is a horizontal section on the two planes indicated by the line XX of Fig. 5, the knobs being removed. Fig. 3 is a face view of the lock roll-backp Fig. 4: is a vertical section of one of the frame-plates and cap on the line y 3/ of Fig. 5. Fig. 5 is a vertical section on the line 2 z of Fig. 8'

looking toward the frame-plate which bears the cylinder-lock. Fig. 6 is a detached inner face view of the frame-plate and connected parts that bear the cylinder-lockwith the-lock roll-back removed. Fig. 7 is a like View of the companion frame-plate. Fig. 8 is an end view of my lock, the knobs being removed.

A designates what Ishall term a frameplate for. the outer side of the door, and B is another and separate frame-plate for the inner side of the door. These plates each carry the latch-operating mechanism. Each plate is provided with a hollow boss 9, within which the shanks or spindles of the knobs 10 and 13 are journaled so as to rotate freely and yet at the same time are held against moving endwise. As shown in Fig. l, I secure these knob-spindles against endwise movement by means of a split ring or collar 11, which is let into a groove .in the stem or spindle 12 of the knob 13, the said split collar being held in place by a ring 1 1.

15 is an end plate connected to the frameplate A and preferably made integral therewith. The latch bolt or head 16, as shown, isan oscillating bolt and is pivoted to the end plate 15 by a pin 17. The latch 16 may be manually forced outwardly by means of the spring 18. In the particular form shown there is on the back or inner side of thelatch 16 an extension-arm 19, by means of which the two separate and independent latch-slides 20 and 21 are operatively connected with the latch-bolt, while the said two slides may be moved without special adjustment toward or away from each other and still remain operatively connected with the latch-bolt. Upon the inner side of the end plate 15 there are two ribs 22. cut away toward one end to form the slots 23 between the said ribs and inner face of the said plate. That edge of the end plate 15 which faces the frame-plate B on the inner side of the door is provided with a rabbet 24, as shown in Figs. 1 and 2.

The frame-plate B for the inner side of the door is preferably provided with a short subend plate 25 and ways 26, that fit the ribs 22 and slots 23, as best shown in Fig. 5, whereby the plate 15 and subplate 25 may slide one upon the other to bring the two frame-plates nearer to or farther from each other to accommodate doors of different thickness. A screw 27, passing through a hole in the plate B into a long boss 28 on the plate A, aids in holding the two plates together when adjusted. After the lock is fitted to the door another screw, 27, of the proper length may be passed through a hole in the plate B and into a threaded screw-hole in boss 31 on the plate A, as indicated in Fig. 1. These plates may be drawn together until the rabbeted edgeof the end plate 15 comes in contact with the inner face of the plate B. When thus adjusted, the lock will fit the thinnest door that it is designed for. For a thicker door a fillingpiece 29 may be employed to build out the one rabbeted edge to fit the rabbeted edge of the end plate, while its other edge abuts against the inner face of the plate B. Screws 30, passing through this filling-piece into the subend plate, hold the filling-piece firmly in place, all as shown in Figs. 1, 2, and 3. For a still thicker door a wider filling-piece may be employed.

The knob 10 is or may be an ordinary doorknob, except that its spindle or stem is journaled in the boss of the plate B instead of (Eating mounted upon any independent spine. 100 there is a knob roll-back 32 for acting on the slide 21, that lies in the rear side of the frame-plate B. The outer end of this slide is bent toward the latch 16 and carries a pin 33 for securing a sliding connection with the extension-arm 19 of said latch.

The knob 13 is provided with a hollow spindle 12, which engages with a roll-back 38, which in turn engages with a latch-slide 20, guided in the frame-plate A, the end of which slide 20 is bent towardthe latch 16 and is connected with said latch by a pin 39, which slidably engages with the extension 19, as shown in Figs. 2, 5, and 6. The knob 13 may thus be employed to operate the latch 16 entirely independent of the knob 10, as well as the latch-operating mechanism controlled thereby and carried by the frame-plate B. The knob 13 may support a cylinder-lock 34 of ordinary construction, which look may have a socket 35 adapted to receive a separate spindle 36, carrying a lock roll-back 37. The socket of the cylinder-lock is concentric with the hollow knob-spindle 12, and through the said spindle 12 passes the spindle 36, carrying the locln'oll-back. When the lock 34 is operated by aproper key, it rotates the spindle 36 and rocks the lock roll-back 37, and thus in a manner-entirely independent of the knob roll-back actuates the latch-slide so as to operate the latch, both roll-backs 37 and 38 being arranged to operate said slide. In this manner the latch 16 may be operated by either a suitable key or by the knob 13.

It will thus be seen that the independent frame-plates each carry complete latch-operating mechanism capable of independent operation. These parts may be held in place by means of caps 40, which may be formed of thin resilient metal with offset flanges41 at opposite edges. The frame-plates A and B may be grooved at 42, Fig. 4, (also indicated by broken lines in Fig. 5,) the said grooves being cut in the horizontal walls of the rim 43 of the said plates. The ends of the flanges 41 may bear against the bottom of said grooves, so as to hold the caps in place friction-tight. These caps may be inserted in these grooves by first entering one edge in one groove and then bending the plate until the other edge comes opposite the other groove, when it will At the inner end of the knob-spindle snap into place, as shown. The resiliency of the metal enables the caps to bend sufiiciently to be thus inserted. In order to remove the cap, it is only necessary to insert a screwdriver or other similar tool between one horizontal wall of the plate and the shoulder of the cap and, bearing on the said tool, force the flange out of the groove.

The frame-plate B has mounted therein a handle or knob 44.

45 is a spindle extending from knob 44.

The plate A has mounted thereon the socketed hub 46, carrying a crank-pin 47 for engaging a slot in the head of a sliding stopbolt 48. By this means the bolt 48 may be moved from the position shown in Fig. 6 toward the right to carry its end into the notch or recess 49 in the knob-spindle 12 to lock the knob 13 against rotation. This lock mechanism is made the subject of Letters Patent N 0. 744,134, granted November 17, 1903, on another application of even date herewith, Serial No. 142,586, and therefore is not claimed herein except in combination.

In putting the look upon the door the edge of the door is cut into only slightly to let in the thumb-turn spindle and to mortise in the end plate and the parts immediately to the rear thereof. The frame-plates rest on the surface of the door on the opposite sides thereof. In adjusting the lock to doors of different thicknesses the end plate and subend plate slide one upon the other in their ways or guides. Since the two separate latclropcrating slides are slidably connected to the latch-bolt, the frames A and B may be moved toward or away from each other without specially adjusting said connection. The knobs 1O 13 are mounted on the frame-plates independently of any spindle passing through the door in the axial lineof the said knobs and independently of any support other than the said frame-plates.

It should be understood that each of the escutcheon-plates A and B constitutes a separate and independent frame in that they each support a complete latch-operating mechanism independently of the other.

The sliding-connection which thelatch-operating mechanism makes with the latch bolt or head 16 may be made so as to have arange of action that will permit the frames A and B to be spaced apart to a sufiicient extent to embrace doors of any thickness.

It is apparent that some changes from the specific construction herein disclosed may be made, and therefore I do not wish to be understood as limiting myself to the precise form of construction shown and described, but desire the liberty to make such changes in working my invention as may fairly come within the spirit and scope of the same.
